Inheritance Of Virulence In The Root Rot Pathogen Phytophthora Sojae, Sirjana Devi Shrestha

Electronic Thesis and Dissertation Repository

The oomycete Phytophthora sojae causes stem and root rot of soybean plants. The interaction of pathogen avirulence (Avr) and host resistance (R)-genes determine the disease outcome. The Avr3a mRNA transcript level is variable among P. sojae strains and determines virulence towards the R-gene Rps3a. To study the inheritance of virulence, genetic crosses and self-fertilizations were performed. A cross between P. sojae strains ACR10 and P7076 causes transgenerational gene silencing of Avr3a allele, and this effect is meiotically stable up to the F₅ generation. However, test-crosses of F₁ (Avr3a^ACR10/Avr3a …

The Phenotypic Effects And Transcript Response Of Salt Stress, The Impact Of Viral Infection On Salt Stress Symptoms, And The Effect Of Salt Stress On Soybean Virus Vector Activity In Soybean Varieties That Vary In Chloride Uptake, Alma Glenn Laney

Graduate Theses and Dissertations

With the increase in saline soils worldwide, understanding the mechanisms for salt tolerance in plants is important to reduce yield loss due to salt stress. Soybean, Glycine max (L.) Merr., genotypes differ in chloride uptake with genotypes that take up chloride into foliar tissues tending to be salt-sensitive whereas those that partially exclude chloride from the leaves are more salt-tolerant. Transcriptional and physiological responses were measured in two soybean cultivars, Clark and Manokin, which differ in chloride uptake in response to salt stress and in combination with Soybean mosaic virus (SMV) and its aphid vector, Aphis glycines . The interaction …

Integration Of Herbicide Programs With Cultural And Mechanical Practices For Managing Glyphosate-Resistant Palmer Amaranth (Amaranthus Palmeri) In Soybean (Glycine Max), Holden Bell

Graduate Theses and Dissertations

Herbicide-resistant Palmer amaranth is the most troublesome weed in Arkansas row crops, causing producers to rely heavily on multiple mechanisms of action to reduce selection pressure for further evolution of herbicide resistance and to successfully produce a profitable crop. It is critical for the sustainability of weed management not only to adequately control this weed but also to reduce the soil seedbank using both non-chemical and chemical practices. Studies were conducted to determine the effect of soybean row spacing, seeding rate, and herbicide program on Palmer amaranth emergence, survival, and seed production in soybean, the effect of drill-seeded soybean population …

Screening Diverse Soybean Germplasm For Water-Logging Tolerance, John Franklin Carlin

Graduate Theses and Dissertations

Water-logging can be detrimental to soybean growth and development; effects range from chlorosis and stunting to yield loss and plant death. Soybean response to, and the effects of, water-logging are dependent on the growth-stage of the plant at the initiation of water-logging. The objectives of this study were to screen a diverse soybean germplasm collection for water-logging tolerance (WLT) at both the V5 and R1 growth stage and to develop a method to screen soybean for WLT in greenhouse. One hundred thirty five genotypes consisting of historical genotypes, PIs, drought and WLT tolerant breeding lines were screened for WLT in …

Agricultural Classification Of Multi-Temporal Modis Imagery In Northwest Argentina Using Kansas Crop Phenologies, Jarrett Alexander Keifer

Dissertations and Theses

Subtropical deforestation in Latin America is thought to be driven by demand for agricultural land, particularly to grow soybeans. However, existing remote sensing methods that can differentiate crop types to verify this hypothesis require high spatial or spectral resolution data, or extensive ground truth information to develop training sites, none of which are freely available for much of the world. I developed a new method of crop classification based on the phenological signatures of crops extracted from multi-temporal MODIS vegetation indices. I tested and refined this method using the USDA Cropland Data Layer from Kansas, USA as a reference. I …

Proteolysis And Lactobacillus Fermentation Effects On The Isoflavones Biotransformation And Removal Of Anti-Nutritional Factors Of Soy Bean, Li-Jung Yin, Hsueh-Ming Tai, Hui-Hung Lee, Shann-Tzong Jiang

Journal of Marine Science and Technology

To investigate the effects of proteolysis and Lactobacillus johnsonii (LAB) fermentation on the removal of anti-nutritional factors and isoflavones biotransformation, soy bean was hydrolyzed by Bacillus subtilis YJ1 proteases and cellulases and further fermented with Lactobacillus johnsonii. Increases in soluble proteins, peptides, free amino acids, daidzin and genistin (p < 0.01) were observed after 10 hr hydrolysis at 50°C. Although no further increases in soluble proteins and peptides (p < 0.01) were observed after 24 hr Lactobacillus johnsonii fermentation in both 5-L and 120-L fermentors, substantial transformation from daidzin and genistin to daidzein and genistein was obtained (p < 0.01). Most of the anti-nutritional factors such as stachyose, raffinose, glycinin and β-conglycinin were not detected, suggesting that the hydrolysis and further Lactobacillus johnsonii fermentation could effectively remove the anti-nutritional factors and transform most of isoflavones into aglycones.

Identification Of Quantitative Trait Loci / Genes For Low-Stachyose And High-Sucrose Content In Soybean Seeds, Sandra Liliana Florez Palacios

Graduate Theses and Dissertations

Seed carbohydrate content is an important aspect in breeding for food-grade soybeans commercialized in the soyfood market. Sucrose and stachyose are the primary carbohydrates in soybean seed. Sucrose affects the quality and taste of various soyfoods such as tofu, soymilk, and natto; however, consumption of soy-based products with high stachyose concentrations can cause diarrhea and flatulence. A mutant line (V99-5089) with high-sucrose and low-stachyose has been identified. The objectives of this research were: 1) to identify sucrose QTLs in a F2-derived mapping population; 2) to investigate the genetic relationship between two low-stachyose sources, V99-5089 and the germplasm line PI200508; and …

Drivers Of Spatial And Temporal Variation In Soybean Yield And Irrigation Requirements In The Western Us Corn Belt, Patricio Grassini, Jessica A. Torrion, Kenneth Cassman, Haishun Yang, James Specht

Department of Agronomy and Horticulture: Faculty Publications

Both rainfed and irrigated soybean production are important in Nebraska (western US Corn Belt), accounting for a respective 48 and 52% of the state’s soybean production of 7 Mt on a respective 55 and 45% share of the state soybean area of 1.9 Mha. To date, no assessment of factors that may account for regional and inter-annual variation in yield and irrigation amount has been performed. To accomplish that objective, we evaluated a database containing on-farm field yields and total irrigation amount used in those fields. These data have been collected annually from ca. 1000 soybean fields in six regions …

Dynamics Of Early-Season Weed Management And Soybean Nutrition, Nick T. Harre

Theses

The popularity of growers using only postemergence (POST) herbicides for weed management in soybean was enabled by the commercialization of glyphosate-resistant soybean. The efficacy and flexibility provided by this technology diminished the use of soil residual herbicides and arguably, increased soybean yield loss from early-season weed competition. While, the rapid evolution and biogeographical spread of herbicide-resistant weeds, especially glyphosate-resistant biotypes, has renewed interest into the use of soil residual products, herbicide-resistant soybean technologies continue to be developed that may once again entice growers into POST-only weed management systems. The commercial interest in soybean yield advancements justifies further characterizing the benefits …

Conference on Applied Statistics in Agriculture

Increased demand for soybean [Glycine max (L.) Merrill] production for industrial, human, and animal consumption has provided many incentives for farmers and producers to increase their production. In many soils used for soybean production, phosphorus (P) becomes a major limiting factor to soybean growth and grain production. A field experiment was conducted in five locations across Eastern South Dakota in 2013 to study the response of soybean yield and yield components to phosphorus fertilizer applications. The experiment was laid out in a randomized complete block (RCB) design with four replications. The treatments consisted of five P levels 0, 20, 40, …

Evaluation Of Forage Soybean Yield And Quality Characteristics And Potential As A Feed Resource For Developing Replacement Beef Heifers, Emily G. Taylor

Open Access Theses

Two agronomic studies were conducted to evaluate the yield and quality potentials of forage soybean (Glycine max ( L .)) grown with and without pearl millet (Pennisetum glaucum (L .)). Results indicate that there were no differences between row spacings of 18 cm or 36 cm and targeted populations of 469,500 seeds ha-1 or 234,750 seeds ha-1 on dry matter yield or overall quality of the forage soybean. While harvest date had significant effects on quality as the crop matured, forage soybean as a monoculture proved to be a very forgiving crop, and recovered in quality as …

Evaluation Of Constitutive Iron Reductase (Atfro2) Expression On Mineral Accumulation And Distribution In Soybean (Glycine Max. L), Marta W. Vasconcelos, Thomas E. Clemente, Michael A. Grusak

Center for Plant Science Innovation: Faculty and Staff Publications

Iron is an important micronutrient in human and plant nutrition. Adequate iron nutrition during crop production is central for assuring appropriate iron concentrations in the harvestable organs, for human food or animal feed. The whole-plant movement of iron involves several processes, including the reduction of ferric to ferrous iron at several locations throughout the plant, prior to transmembrane trafficking of ferrous iron. In this study, soybean plants that constitutively expressed the AtFRO2 iron reductase gene were analyzed for leaf iron reductase activity, as well as the effect of this transgene's expression on root, leaf, pod wall, and seed mineral concentrations. …

Food For Thought: Genetically Modified Seeds As De Facto Standard Essential Patents, Benjamin M. Cole, Brent J. Horton, Ryan G. Vacca

Akron Law Faculty Publications

For several years, courts have been improperly calculating damages in cases involving the unlicensed use of genetically-modified (GM) seed technology. In particular, when courts determine patent damages based on the hypothetical negotiation method, they err in exaggerating these damages to a point where no rational negotiator would agree. In response, we propose a limited affirmative defense of an implied license due to the patent’s status as a de facto standard essential patent. To be classified as a de facto standard essential patent, the farmer must prove three elements that reflect the peculiarities of GM seeds used in farming: (1) dominance, …

Soybean Peroxidase Catalysis In Removal Of Anilines And Azo-Dyes From Water, Samar Mazloum

Electronic Theses and Dissertations

Azo-dyes are the largest group of colourants produced, and they are applied in many industries. In the environment they are recalcitrant, and under anaerobic conditions can break down to toxic or even carcinogenic aromatic amines. Aerobic treatment of azo-dye-contaminated waters has been shown to be ineffective. Thus, enzyme-catalyzed polymerization and precipitation of azo-dyes and their reduction products was studied and optimized in this dissertation. Additionally, zero-valent iron reduction of azo-dyes under anaerobic conditions followed by soybean peroxidase (SBP) enzymatic treatment was investigated. The use of additives to reduce enzyme requirement and enhance the removal of anilines was also studied. Azo-dyes …
